Question

A body starts from rest and moves with a uniform acceleration of 5m/s what will be the velocity when it has covered a distance of 250m?

Answer 1

Answer:

50 m/s

Explanation:

v² - u² = 2as

Since initial velocity is equal to 0.

= v² = 2as

v² = 2 × 5 × 250

v² = 2500

v = 50 m/s

Answer 2

Answer:

Given ,

u = 0

v = ?

S = 250 m

a = 5 m/s

Formula used ⇒ v² - u² = 2aS

v² = u² + 2aS

   = 0 + 2×5×250

   = 2500

v = √2500

  = 50 m/s

Hence , the velocity of the body will be 50 m/s

Hope it helped :)
